If you’ve ever worked with a database, you’ve likely worked with CRUD operations. CRUD operations are often used with SQL, a topic we’ve covered in depth (see https://stackify.com/view-sql-with-prefix/, https://stackify.com/measure-real-world-sql-performance-asp-net/, and https://stackify.com/writing-better-sql-queries/ for some of our recent SQL tips and tricks). Since SQL is pretty prominent in the development community, it’s crucial for developers to understand how CRUD operations work.

Here’s an example SQL procedure for CRUD operations on customer data.

WHERE id = ?', [data, id], (err, res) => { if (err) throw err; console.log('Data updated:', res.affectedRows); }); } function deleteData(id) { connection.query('DELETE FROM your_table WHERE id = ?', [id], (err, res) => { if (err) throw err; console.log('Data deleted:', res.affectedRows); }); } Use the functions we just built to perform CRUD operations const data = { name: 'John Doe', age: 30, email: 'https://stackify.com/cdn-cgi/l/email-protection' }; // create new data createData(data); // retrieve data retrieveData(1); // update data updateData(1, { name: 'John Doe' }); // delete data deleteData(1); Using SQL Procedures with NodeJS
